Mercury may need salt glaciers that could create the conditions essential for life kilometres underground. These rock salts might encircle the total planet, and could rework our picture of Mercury as a barren wasteland.
In area, easy-to-vaporise compounds similar to water and salts are known as volatiles. Historically, scientists have believed that Mercury largely lacked volatiles due to the excessive temperatures that outcome from its proximity to the solar and lack of environment. However, in latest a long time, they’ve found…
